3 Claims.

This invention has general reference to safety pins and comprehends an improvement in this class of pins by virtue of which the safety factor thereof is materially increased while rendering the pin capable of use for effectively pinning together relatively different "thicknesses of mate rials. p p

The invention is directedmore particularly to an improved head structurefor safety pins which is so constructed and arranged as to provide a plurality of terminal hooks disposed in reversely arranged spaced nested relation to define amultiplicity of catches, one enclosed by the other whereby accidental displacement of the terminal of the piercing leg from the innermost terminal hook, when engaged therewith, will result in a subsequent automatic engagement thereof with the next adjacent outer catch or hook.

A further feature of the head construction heretofore described renders the pin capable of multiple use by extending or increasing its range or capacity, as it is apparent that by selectively engaging the piercing leg with the several hooks or catches, the distance between the legs of the pointed out in the appended claims, while the same is illustrated in the accompanying drawing,

wherein: Fig. 1 is a perspective View of a safety pin constructed in accordance with the present invention.

Fig. 2 is an'enlarged vertical sectional view through the head of the pin, taken approximately on the line 2-2 of Fig. l,showing the piercing leg engaged with the inner hook or catch.

Fig. 3 is a similar view illustrating the piercing leg engaged with the outer hook or catch.

Fig. 4 is a perspective view illustrating a modified form of the invention.

Referring to the drawing by characters of reference, the pin which is fashioned from a length of resilient wire is formed to provide an intermediate coiled portion l and a pair of normally divergent legs II and I2 extending tangentially therefrom in the same general direction and ten sioned against movement of the free ends thereof toward each other. The leg I2 which is hereinafter designated the piercing leg is formed with a pointed terminal I3 at the free end thereof which is adapted to engage with ahead or keeper element I4 secured to the free end of the other leg II. The head I4 which is constructed of sheet material is bent and formed to provide a pair of leaves I5 and I6 extending from said leg I I in the direction of the other leg and arranged in spaced side-by-side relation. The leaves I5 and I6 are formed with reversely arrangedspaced concentric arcuate terminals I7 and I8 nested or arranged one within the other to provide hooks or catches With which the pointed terminal I 3 of the piercing leg I2 is adapted to be selectively enhead supporting leg I I but which are separated from each other and lie on opposite sides of the leaf I5. It thus follows that when the pointed terminal I3 of the piercing leg I2. is engaged with the innermost hook or catch I7, the leg I2 must be moved toward the leg I I against the tenslon, then shifted laterally after passing through the entrance mouth I9 thence between the outer surface of the inner catch and the inner surface of the outer catch l8, after which said leg I2 is shifted laterally after passing through the entrance'mouth 29 of the outer catch, in order to disengage the piercing leg I2 from the head M of the pin. It will also be observed that this increases the safety factor due to the fact that if the piercing leg should he accidentally released from the inner catch I'l, it will be caught by the outer catch Iii.

It is apparent that when the piercing leg I2 is engaged with the outer catch 58, it will be spaced at greater distance from the head supporting leg II than when the piercing leg is engaged with the inner catch I'I, hence this varies the range or capacity of the pin so that when it is engaged in the outer catch it will accommodate a greater amount of material to be pinned than when it is engaged with the inner catch.

In the modified form of the invention illustrated in Fig. 4 of the drawing, the construction of the head or keeper element is substantially identical with that of the preferred form,

with the exception that in this instance an ad-v ditional leaf 25 is employed which is secured to the leg l I and extends therefrom in the direction of the piercing leg. The leaf 25 is arranged in side-by-side relation to the leaf I5 and is formed with an arcuate terminal 26 disposed in spaced concentric nested relation to the arouate terminal [8 anddefines an entrance mouth 2! facing toward the supporting leg II on the opposite side of the head from the entrance mouth 20 and separated from the entrance mouth l9 by the'leaf [6.

What is claimed is:

A safety pin including a pair of connected e sione or no m lat v separ t n of the free ends thereof, one of said legs const ituting a piercing leg having a pointed extremity a head secured to the free end portion of the other leg and constructed to provide a pair of leaves extending from said leg in the direction 1 of the other leg and arranged in spaced sideby-side diverging relation, said leaves having reversely arranged spaced egncent ig J312-3J2$ terminals defining retaining hooks nested one within the other and with which inner hook the oint d ext e it o th memes e s e an e e il an isee es 'b Pass ge (e 'is enem ,h 1 e 'tn u erhs s the email f sa d .l s'b m a rted to 1 c i. l h p e c n e ii into a a at th se f ai hbb s s when the same e g ed. wit h a a et p n, a l ng a es lie t i e forme to, ro id a Win9 te me t port on and a a r 9 normally di e 5 attendin refr m in the amswrd d nes... nd ons gai s maven??? of the free nds th eof a d t eth other, a 29ld te lmm iflat-t ie re e d 9f ee and. h a s cu ed to the r e an Pe sm 9? the oth r e intera te t9 pr vi e a a r o l ves extend n item S n t e di ction o t e othe lee and enema in spaced side byeside relatiq said leaves having reversely arranged spaced concentric arcuate terminals defining retaining hooks nested one within the other and with which the pointed terminal of the piercing leg is adapted to be selectively engaged and retained by the tendency of said leg terminals to normally separate, said piercing leg terminal being engageable with the inner hook and disengageable from the head only after passing of the same under the outer hook. 3.
